[update] TeKoMed Workshop in Lübeck

October 25th, 2011

For the 3rd time, the TeKoMed-Workshop will be held in Lübeck. This year it will be a two days event from 7th to 8th of November 2012. Objective of the workshop is the usage of Service-oriented principles in the domain of medical devices, mainly focusing on device integration in medical institutions like for example hospitals.  Of course, everybody is invited to participate! Find more informations on the workshop website.

[update] For those interested in the slides of the presentations, you can download them on the workshop website of the TeKoMed Workshop. [/update]

WS4D @ IoTech Workshop

October 17th, 2011

On October 17th, the International Workshop on Internet of Things Technology and Architectures (IoTech) was held in Valencia/Spain, co-located with the IEEE MASS conference. The objectives of the workshop read like the who-is-who of several WS4D efforts: IPv6, 6LoWPAN, RPL, CoAP, EXI , IEEE 802.15.4, IoT, WSN etc. So also WS4D joined the IoTech and presented the SOAP-over-CoAP approach. But you might find other things among the presentations.

[Update] 6th IEEE SOCNE Workshop

April 29th, 2011

The 6th IEEE International Workshop on Service Oriented Architectures in Converging Networked Environments (SOCNE) has been be held in conjunction with 16th IEEE International Conference on Emerging Technologies and Factory Automation (ETFA’2011) in Toulouse, France, 05.  September 2011.

The scope of the SOCNE workshop is on not only on SOAs in general, but also on (resource constrained) device centric environments, including H2M and M2M scenarios. And of course the REST folk is welcome as well :).

For more information visit the workshop website http://www.socne.org.

[Update]

The proceedings of the SOCNE workshop are now available on www.socne.org. From those presenters who kindly sent us theire files, we also published the accoring slides to the papers.

The next ETFA 2012 will be held in Krakow/Poland. This is probably one of the most beautiful cities in Europe and thus maybe also the venue for SOCNE 2012?!?!?!

Announcing WS4D-JCoAP

April 14th, 2011

WS4D JCoAP

May we introduce? User CoAP, CoAP user. The Constrained Application Protocol (CoAP) is an exciting emerging protocol defined by the IETF CoRE WG, currently in the state of an Internet Draft. To put things short, CoAP is supposed to create an alternative to HTTP for RESTful APIs on highly resource-constrained devices. While HTTP usually bases on TCP, CoAP defines rudimentary reliability features so you can run it on UDP and therefore save a lot of protocol overhead that inherently comes with TCP.Now that you have an idea of what CoAP is (if you hadn’t already) we want to share our latest efforts on implementing CoAP. WS4D-JCoAP is supposed to be the first (as far as we know) feature complete CoAP implementation in Java. By this time, we managed to implement a simple CoAP Client application. Within the next days and weeks, we plan to implement a higher-level connection API supporting automatic retransmission and recognition of duplicate messages as well as the whole server side.If you are curious right now or want to support us, check out the google code repository. Have fun!

The CeBIT 2011 is over. Welcome CeBIT 2012.

March 10th, 2011

University of Rostock

The CeBIT 2011 is over and we proudly showed what is possible with the WS4D frameworks. An Pulse/SpO2 sensor using 6LowPAN and a remote controlled window live from the Embedded 2011 were the highlights.
We showed the total lineup from small devices using the uDWPS up to the newest App for Android using the JMEDS Stack.
PipesBox was used to control the window via a twitter API. That was awesome. Feel free to use our open source stacks and get infected by the web service idea and get curious for the CeBIT 2012.

WS4D Smart-* Demonstrator

February 21st, 2011

As we already posted, the CEBIT in Hannover and the Embedded World on Nürnberg are getting closer. So we posted a preview on the CEBIT demonstrator a few days ago, showing WS4D-uDPWS in action (see the SpO2 finger clip sensor).

Now would like to give a preview on the Embedded World demonstrator here. The video shows our Smart-Window, opening and closing depending on the humidity. The involved technologies are 6LoWPAN, IPv6, CoAP, DPWS, Digitalstrom and several of our existing WS4D tools. Feel free to comment…

WS4D @ IETF80

February 21st, 2011

In January, the Internet Architecture Board announced the ‘Interconnecting Smart Objects with the Internet Workshop‘ to be held in conjunction with the IETF80 in Prague. While the workshop requires a selection of participants, the additional held ‘Tutorial on Interconnecting Smart Objects with the Internet’ is open for everyone. WS4D will join both the workshop and the tutorial. So feel free to join the tutorial and meet the strange IETF folk in Prague!

Background: WS4D participates in the IETF mainly in the 6LoWPAN and CoRE working groups, published I-Ds about DPWS for 6LoWPAN and SOAP over CoAP and has developed WS4D-uDPWS, an Open Source DPWS stack for mote class devices.

WS4D-uDPWS SpO2 Sensor over 6LoWPAN and Remote Android App in Action

February 11th, 2011

This is nerdy! We will present our SpO2 sensor running WS4D-uDPWS over 6LoWPAN on an AVR Raven at Cebit 2011 in Hannover. Here is the preview:

The next step towards Web services in 6LoWPAN networks: SOAP over CoAP

January 26th, 2011

Since the movement towards the Internet of Things and Smart Objects is gaining in momentum more and more, WS4D is proud to contribute to this field. Therefore an Internet Draft is published in the active IETF CoRE working group, describing an approach to bind SOAP to the CoAP protocol. Since CoAP is currently in draft state, the SOAP-over-COAP is it of course also. Nevertheless, contributions and feedback to the draft are more than welcome. Find the draft at http://tools.ietf.org/html/draft-moritz-core-soap-over-coap.

Meet WS4D @ embedded world 2011

January 25th, 2011

The University of Rostock exhibits on the embedded world in Nürnberg (01.03. – 03.03.2011) and promotes WS4D technologies to overcome the problems of the heterogeneous hardware structure with advanced cross domain solutions. See the “Internet of Things” and make your first experiences with WS4D. We will present you:

  • A complete overview about the WS4D technologies and its potentials for the creation of smart cross domain systems.
  • Advanced software toolkits for WS4D development with C/C++ and Java.
  • The WS4D-PipesBox tool for the easy graphical creation of device ensembles and service mashups.

We will demonstrate the power and  simplicity of WS4D in the domain of Home Automation (Smart Objects, digitalStrom).

Miscellaneous contacts already have been established and hopefully more potentials partners from industry and for research will follow during the following days. Come and see the live demonstration of the WS4D capabilities and meet the team. Visit us at Hall 11, 11-128 with the exhibit “WS4D – Web Services for Devices – Cross domain technology for smart systems.
